Both the front... - Page 12 Honda VT750DC ACE Free Play: Whenever pedal height is adjusted or when the rear brake is getting worn, you should check and adjust the free play at the brake pedal. Measured at the tip of the brake pedal (3), free play should be kept between 20‐30mm (0.8‐ 1.2in). Make free play adjustments by forcing the brake arm forward (5) and then turning the adjusting nut (4). Turning it in the direction of (A) decreases free play while turning it in the direction of (B) increases free play. Make sure the adjusting nut cut‐out is seated on the brake arm (5) when finished. WARNING: It has been my experience that this adjusting nut can back off on it's own (perhaps due to the increased vibration of my aftermarket pipes) and I had a near disaster on the 401 HWY once when it backed off so far that I had no rear brakes. I would recommend installing a second 'jam nut' behind this adjuster. I installed a fiber lock nut as a jam nut and it has not moved at all since then. 12 Service Interval and Recommended Maintenance Manual ...

Page 65: Task #31 - Pilot Screw Adjustment
Honda VT750CD ACE Task #31 - Pilot Screw Adjustment The carburetors on the ACE have what is called Pilot Screws that set the air/fuel mixture for when the engine is at idle. These screws are set at the factory and then covered with brass plugs and normally, no adjustment is necessary on them. - Page 66 Honda VT750DC ACE Step 2: Remove the plug covering the pilot screw on the left carb (rear cylinder - see Pic). A good way to do this is to drill a small hole in the plug (be careful that you only drill just enough to get through the plug and not into the screw behind it!).
